Description

This is circuit schematic diagram of Elegant Bathroom Mirror Lights Using Motion Detector that can help you to build elegant bathroom mmirror lights. The main component in this circuit are IC regulator 7805 and motion detector. 

According Electroschematics site that the first part of the schematic is a transformer-less DC power supply for converting the 230-V AC input to about a 16-Vdc output. This DC output is used to power the rest of the electronics, excluding the motion sensor. The very popular, yet cheap, DYP-ME003 PIR sensor module is used here for the detection of human motion. Refer to its datasheet for technical specification, calibration information, etc. Because the module has a provision to attach one light-sensitive resistor (LDR/photoresistor/CdS cell), a 5-mm standard LDR is attached to the module after a minor mod. This drives the switch to be operational only when the detection area is sufficiently dark (the mirror lights up when one enters the darkened bathroom). For this, just detach the fresnel lens of the module, carefully solder the LDR on the vacant pads denoted as “CdS,” ensuring that it faces toward the fresnel lens, and retain the fresnel lens in front. Next, flip the module to replace the 1M (105) SMD resistor with a 100K (104) SMD resistor. Note that one end of this resistor (and one lead of the photoresistor) is linked to “trigger disable” (pin 9) of the BISS0001 IC. The other end of the resistor is tied to the 3.3-V (Vcc) rail, whereas the second lead of the photoresistor is connected with the 0-V (GND) rail.
